DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 233,542, dated October19, 1880.

Application filed August 16, 1880.

To all whom it may concern Be it known that I, WILLIAM H. PAIGE, of

Springfield, in the county of Hampden and ing my invention applied.

State of Massachusetts, have invented a new and useful Improvement inDump-Oars, which has not been patented in any foreign country to anyperson with my knowledge and consent, of which the following is aspecification.

The object of my invention is to provide a railway-car from which thewhole contents may be easily and quickly dumped from either side bymanipulating the mechanism connected therewith, and which is illustratedin the accompanying drawings, in which- Figure I is a side view of adump-car hav- Fig. II is a plan view of the frame of the same having themechanism applied. Fig. III is an end view of the car. Fig. IV is avertical longitudinal section of the car, showing the shipping lever androd which operates the side bearing, and the clutches which areconnected with the winding-shaft, and showing the side bearing thrownup, with the forward clutch thrown out from the winding-drum. Fig. V isa vertical longitudinalsection through the hunter-socket. Fig. V1 isavertical longitudinal section, showin g the clutch-operating rod, whichalso moves the side bearing, and with the latter in its verticalposition. Fig. VII is a front view of the buffer-socket, and Fig. VIIIis a front view of the braces between which the buffer-socket revolves,and by which it is held in place.

In the drawings, A represents the two side sills of the car, and O 0represent two other inside sills or timbers, all extending in adirection lengthwise the car, and to which are secured the cross-timbersand floor-boards of the car, and to the lower side of the car, orbeneath the floor, are secured suitable bearings, in which are arrangedto revolve easily the shafts 14, one on each side, extending lengthwisethe car, on each of which shafts is a drum, 8, arranged to revolvefreely on the shaft. Two clutchesone, 6, on one side of the drum, andanother, 7, on the other sideare so keyed to the shaft as to revolveonly with the shaft, and so as to slide to and fro along the shaft andengage with the drum by teeth or projections on the clutch and also onthe sides of the drum, and cause the drum to (No model.)

revolve, according as one or the other clutch is brought up against thedrum.

A rod, 2, is arranged to move longitudinally in suitable bearings neareach shaft, upon which rod is a projection, 5, to engage with and movethe clutch 6 to and fro along the shaft, and also a projection, 9, tomove the other clutch, 7, along the shaft in the same manner, and theseclutches are so adjusted with reference to the rod2 that when one clutchis in engagement with one end of the drum the other clutch is moved awayfrom the other end, say, from six to eight inches, and the rod 2 at theend of the car is connected with a pivoted lever, 1. This rod 2 is alsoconnected, by an arm, 4, with a pin or arm on the side bearing, D, whichis a heavy metallic piece suspended from a shaft or pivot, 20, securedto the bottom of the car, one of these bearings on each side of the carat each end, its lower end resting on the truck-beam and this sidebearing, D,is so connected to the rod 2 that when the latter is movedforward to engage the clutch 6 with the end of the drum 8 the sidebearing is held in a horizontal position, as shown clearly in dottedlines in Fig. IV; but when the rod 2 is moved back to engage the clutch7 with the other end of the drum the side bearing, 1), is held in avertical position, so that the weight of the car and its contents willbe supported on that side on the truck-beam, as shown clearly in Fig.VI.

The shaft 14 is provided at the end of the car with a toothed wheel orgear, 11, engaging with a worm or screw on the lower end of the verticalshaft 10, with a winch or handwhcel 011 top, so that by turning thehandwheel or the shaft 10 the shaft let beneath the car will berevolved.

A dog, 12, is pivoted to the lower side of the car and is attached to arod, 15, extending along beneath the car, at the side, which rod is soconnected with any desired number of latches, 16, that when the lowerend of the dog is moved inward and upward the inner end of the latchwill be raised and its outer end depressed, to permit the side wall ofthe car, which is pivoted at a, to swing outward.

The ear is pivoted at E to the truck at each end, so as to tilt toeither side, and the buntor-socket 17 is secured at each end of the carto and between the sills I. This hunter-socket consists of a circulariron, 17, having an annular groove or channel around the outside, intowhich are fitted so as to move freely the projections 18 of the braces21, which are bolted one to each sill, at each side the socket l7, and aprojection on the iron 17 strikes against oneof the projections 18 whenthe socket is turned in either direction, to limitthe rotary movement ofthe hunter-socket to, say, an arc of about thirty degrees.

The rod 2, side bearing, 1), and connections, and operating-lever 1, theshaft 14, and triprod are all duplicated, all these being arranged foreach side of the car, so that the latter may be dumped either way ortoeither side.

Todump the car the operation is as follows: The lever 1 is moved intothe position shown in -Fig. IV on the side on which it is desired todump the ear, raising the side bearing, D, into a horizontal positionand moving the clutch 6 up into engagement with the drum 8, and thelever 1 on the opposite side is moved just sufficiently to move theclutch away from the drum on that side, so that that drum will revolvefreely and rapidly on the shaft. The hand-wheel on the shaft 10, on theside on which the car is to be dumped, is then turned, revolving thedrum and winding up the rope or chain, and thereby drawing down thatside ot'the car, (the end of the chain or rope being made' fast to thedrum and extendingdown and around a pulley or roll in the truck-frame,thence outward along the truck-frame and around another roll, and upwardto theouter sill of the car, where it is made fast,) and tiltiug'the caron its pivots at E. When this windingup of the chain or rope hasproceeded far enough to throw the center of gravity of the load outsidethe pivot E, the lower side of the car will then drop of its own weight,the chain unwinding. rapidly from the opposite drum, and the droppingside striking with a jar against the end F of the truck beam or frame,and the inside sill, 0, also striking against a cushion or block, 22, onthe truckframe, just before the sill A strikes the end of the truck-beamat F, too great a jar or shock is prevented. As the dropping sideof thecar passes down theend ofthe dog 12 strikes against a plate, 13, on thetruck-frame, and the dog is thereby quickly thrown inward and upward,

tripping the latches 16, (of which there maybe mechanism of the car isadjusted to a certain extent the weight of the car or itscontentsisutilized to complete the dumping operation, which is accomplishedwithajar, which will efl'ectually and completely empty the ear, and

this operationand its results differ very essentially from those inwhich the car is gradually and slowly pulled over, or tilted graduallythrough the whole movement, and the dumping is made much more effectual.

WVhen the car is tilted back again, by windingup the opposite chains theside of the car swings in again by its own weight, and is locked by thelatches 16 automatically by the weight of the dog 12 in swinging down.

If one car is dumped and the next one to which it is coupled remainsstationary, the two hunter-sockets 17 will partially rotate between theprojections 18, so that all strain on the coupling will be removed, andyet the socket cannot rotate sufliciently far to lose out the link-pinwhich secures the cars together.

it will be seen that as the side bearing, D, is pivoted at its upper endto the bottom of the car, when its lower end rests upon the truck-framethere will be sufficient movement ofthe bearing-on its pivot as the carisbeing moved upon the road to allow ot' the differences of relativeposition between the car and its trucks in rounding curves, and yet theload will be fully supported by the bearings. As

the chains are kept wound up on the drums,

and the side bearings are provided with this forward and backplay, thereis little or no friction of the bearin gs on the truck-frame, and thecar is effectually prevented from be ing accidentally dumped duringtransportation.

Having thus described my invention, what I claim as new is-- 1. In adump-car, the combination, with each side bearing pivoted at its upperend to the car, of the longitudinally-moving rod 2, the pivotedrod-operatinglever 1, and the arm 4. connected at one end with said rodand at the other end with the side bearing, whereby the latter is movedinto and out of supporting connection between the car and the truck,substantially as described.

2.
